Generate arbitrary beep in Android

Question

as far as I know, there is no simple way in Android to generate a beep (equivalent to Console.Beep(int frequency, int length) in .NET). The only one that looked promising - ToneGenerator class, can generate only a limited selection of tones.

Do I have to generate a waveform by hand, push its data to AudioTrack and play it or is there a library or open source code that does it?

I froze the project and focused on another, until there's time to do more research on this subject — Axarydax, Mar 30 '11 at 06:59

I've been looking for the same. Found on this very site an answer:

Calculate numbers for a waveform with a given frequency
Convert the resulting array to PCM format
Feed AudioTrack to play it back.

That's a good start.

I don't have the URL but you will find the code easily in FAQ looking for someone asking for "...arbitrary frequency"
